Calibre freeware - The Latest User Reviews

Calibre 0.8.3

(May 31, 2011)

This software is now fundemental to how I manage my Kindle. I've only been using it for a couple of days (only had my Kindle that long) but it has handled everything I've thrown at it, in terms of book formats, and converted to mobi.
The Newspapers download is really good for storing and perusing at your leisure.
An excellent piece of s/w - just made a donation - hope you keep up the development, although I can't see how you can improve on it :)
